It’s possible, but if so that information isn’t currently in the docs for the endpoint, and it is not in my head, either! That’s why I thought I’d ask if @joecrotchett was seeing something that could be attributed to age of the DMs.

It could be attributed to the age of the DMs. The five DMs that I was getting back date back August 2014, so I just added six new DMs to my account and now I’m getting back eleven DMs total. I’m still not getting back any of the DMs before August 2014, but I don’t think that’s a big deal. I’m going to move forward with the assumption there’s a time frame on DMs. Thanks for all your help, fellas!
